RAILWAY-SIGNAL.

SPECIFICATION forming part of Letters Patent No. 228,683, dated June 8, 1880.

Application filed March 19,1880. (No model.)

To all whom it may concern:

Be it known that I, ALEXANDER J. ROSE, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Railway-Signals, of which the following is a specification.

The object of my invention is to provide a cheap, simple, durable, and reliable automatic railway signaling apparatus, whereby the wheels of the railway-train passing over the track shall contact at certain points with pivoted arms and operating lever or levers, so as to unlock, disengage, or wind clock-work or any other desired signaling mechanism, whereby such signals may be caused to operate, as hereinafter more fully described and set forth.

Figurel represents a perspective view, showing a railway-rail with my invention connected therewith. Fig. 2 is a side elevation of the same with lever removed. Fig. 3 is a perspective view of the central chair. Fig. 4 is a plan view of the actuating-lever removed. Fig. 5 is a perspective view of one of the end chairs.

A represents the railway-rail, of usual contraction, to the outer side of which are arranged suitable chairs B, at such distance apart as may be desired. These chairs are secured to the ties as heretofore, and are provided with a suitable groove or vertical slot at their upper end to receive one end of the bars 0, which are pivoted therein with their upper edge or face slightly below the face or tread of the rail, and extend parallel alongside of the same, and on a slight incline, so as to project above the rail at the opposite end sufficiently to communicate to the short end of the pivoted actuating-lever D the desired .movement downward. furcated' a "irfreeends, or otherwise formed so as to conntt svith the short end of the actuatin g-lever D, which is arranged at right angles to the bars 0, and is-pivoted to the central chair-block, E, which is formed in two parts or These bars 0 are bi halves and interlocked or dovetailed together at its base, each half being provided with projections or vertical ears, between which the' actuating-lever D perfectly secure and durable, I form said pivots H rigidly with the actuating-lever D by casting or forging them therewith, and then make the connection thereof by passing each half of the central chair upon the same, suitable holes being formed in the ears or vertical projections to receive them.-

It will be seen that the bars 0, which extend each way from the lever D alongside of the rail, are exactly alike or counterparts of each other, and are both operated upon simultaneously by each wheel of a train of cars passing over the same rail and in either direction.

Haying thus described my invention, what I claim is 1. The combination, with the rail A, of the two parallel reverse incline bars 0, pivoted to the chairs B, their meeting ends extending above said rail, and each connecting, by means substantially as set forth, with the short end of the central actuating-lever, D, extending at right angles to the said bars and rail, substantially as shown and described, as and for the purposes set forth.

2. In combination with the rail A, incline bars 0, and actuating-lever D, provided with the pivots, as described, the chair E, formed in two parts or halves and interlocked together, substantially as described, as and for the purposes set forth.

ALEXANDER J. ROSE.
